RFID tags

Subject: Science

Section: Computer related

Context: Amarnath Yatra pilgrims to be tracked through

Concept:

  • Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object.
  • RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC methods automatically identify objects, collect data about them, and enter those data directly into computer systems with little or no human intervention. RFID methods utilize radio waves to accomplish this.
  • At a simple level, RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags contain an integrated circuit and an antenna, which is used to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data. Information collected from the tags is then transferred through a communications interface to a host computer system, where the data can be stored in a database and analyzed at a later time.

Possible applications:

  • Asset Tracking
  • People Tracking
  • Document tracking
  • Inventory management
  • Asset tracking
  • Personnel tracking
  • Controlling access to restricted areas
  • ID Badging
  • Supply chain management
  • Counterfeit prevention (e.g. in the pharmaceutical industry)
  • Libraries
  • Animal tracking
